We ordered the Kattop 660 drone and it worked fine, range was good and it was able to easily carry the weight. Our biggest gripe is that it is NOT a 4K video camera. They advertise 4K, it is only 1440p. The 4K they are referring to is for photos not video. 4K means video (at least here in the US). If you are okay with 1440p then it is a great buy otherwise just use your own camera for video.
